SPRING BED-BOTTOM.

SPECIFICATION formingpart of Letters Patent No. 553,412, dated January21, 1896.

Application filed Au ustin 1898. Serial No. 483,399. (Nomo lelfl T0 @ZZwhom zit may concern:

Be it known that 1, Josnrn 1. Lneenr'r, a citizen of the United States,residing at Carthage, in the county of Jasper and State of Missouri,have invented certain new and useful Improvements in Spring Bed-Bottoms;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters of referencemarked thereon.

The present invention relates to springbeds, and aims to provide a bedof the class employing volute spiral springs, which, while being amplyyielding and comfortable, shall have the springs securely held frommovement out of their proper places, and this by means both simple andeasily employed.

To this end said invention consists in the spring-bedhaving theconstruction hereinafter described, and illustrated in the drawings, inwhich Figure 1 is a plan view of a portion of a bed made in accordancewith my invention; Fig. 2, a detail perspective view.

In the drawings, A designates the volutc springs whose lower ends areattached to intersecting wires or bars B B, as shown in my Patent No.434,794, or to any other suitable support, my present invention havingnothing to do with this portion of the bed. The upper coil of eachspring A is formed with a lateral bend on one side of the spring,providing an offset (1 and the free end is carried in a loop a at theother side of the spring over, under and over the adjacent innercoil,and then the free end passes under itself in a straight arm a under thetop coil of the adjacent spring, to the offset of which and to thesuperposed offset 0 of a stay-rod C it is fastened by an upward bend acrossing and embracing the oifsets between the coil and stayrod. Thebend a is formed with a pendent extension a having a hooked extremity a10- cat-ed beneath the stay-rod.

It will be observed that the stay-rod passes above the top coil of thespring and not under the same; thus avoiding the interlacing that thelatter would necessitate and the consequent troublesome bending of therod or spring or both, in order to firmly secure these two together.lVith my construction the rod is bent only the triflin g amount neededfor the passage of the bend a, and yet the parts are rigidly held by thelatter.

- There is a stay-rod for each line of springs, and said rods run inparallel lines from one side of the frame D to the other and lengthwisethereof, and in a direction at right angles to the direction of thestraight extension of the top coil of one spring to an adjacent one. Itwill thus be seen that a line of springs in one direction is connectedby these extensions, and that a line in a direction at right angles bythe stay wires or rods 0, so that all of the springs are connected, anda smooth and substantial mattress-engaging surface is provided.

By means of the loop a the top coil of each spring is held to place bythe next coil, while the connection of one spring with an adjoining one.and a stay-rod in the manner described absolutely holds the spring frompermanent lateral displacement, although permitting all neededvibration. Each spring is thus securely held in proper position relativeto the others.

The outer line of springs on one side, instead of having the free end ofthe top coil carried to the adjacent spring, have said end first loopedaround the adjacent coil, as with the remainder of the springs, and thenbent around the side bar of the frame D. A link or bar E is employed toconnect each spring of such outer line to a stay rod or wire 0, intersecting the inner side of the top coil and theadjacent spring whereit intersects with a stay rod or wire 0, the ends e of said links beingsecured precisely as are the free ends of the upper coils of the othersprings, as above described.

It will be seen that I have a strong and durable bed, and yet withal onethat is simple and easily made, and not apt to get out of order.

What I claim as new, and desire to secure by Letters Patent, is-

1. A coil spring for bed-bottoms in which the wire extends beneath thetop coil, then directly between the top coil and itself, and then in theform of an extended horizontal arm, whereby the arm is fastened to thetop coil while it is free to slide thereon; substantially as described.

2. A coil spring comprising a top coil having its free end carried overthe adjacent inner coil, then under it then over it, and then underitself on the outside of the top coil to provide a single loose loop aand formedwith a straight arm a and with an upward bend a having apendent straight extension (1 provided with a hooked extremity 05extending parallel With the straight arm; substantially as described.

3. The combination of a coil spring having a top coil formed with asingle offset a the stay-rod having a single offset 0' crossing the coilofiset and a coil spring having a connection formed with a straight arma extending under the coil-ofiset and with an upward bend a hooking overthe crossed offsets, between the top-coil and stay-rod, having a pendentstraight extension to extending beyond the arm; substantially asdescribed.

hereunto subscribed my name in the presence of two witnesses.
